Abstract
A memory device includes a memory array, a processor, and a decoding apparatus. The processor is coupled to the memory array and configured to read encoded data from the memory array. The encoded data includes a plurality of data blocks and each data block is included in two or more data codewords. Further, data codewords belonging to a same pair of data codewords share a common data block. The decoding apparatus is configured to iteratively decode data codewords using hard decoding and soft decoding, and to correct stuck errors by identifying failed data blocks based on shared blocks between failed data codewords.
